Hi Lahaine, Nothing wrong in looking at and admiring another guys penis. We all have an innate natural curiosity to see what the other guy has compared to ourselves. Lets face it how often do we get the opportunity to look and examine a guy at close quarters, not that often if in fact at all.
Dont beat yourself up your not the only guy in the world that likes to see what other guys have got and what it looks like. It don't mean you are seeking any form of sexual gratification from it. Just relax and enjoy, the wonders of the internet have made it possible, causing nobody any harm.
By the way I have to say you have one hell of a cock and how do I know that, because like you I have seen thousands via the internet. Even though I am gay, not evey penis gets me aroused, in fact very few do . You need the magic of the chemistry and sexual tension as well.
Hope this helps
